The Islamic Culture and Relations Organization (ICRO) is hosting the event which features the resistance of the Palestinians in the Gaza Strip.
During the conference, ambassadors from 13 countries will be honored. These are countries that recalled their ambassadors from Tel Aviv in protest to the Zionist regime's atrocities in Gaza, Fars news agency reports.
ICRO chief Abuzar Ebrahimi Torkaman, Palestinian Ambassador to Iran Salah al-Zawawi, and representative of the Palestinian resistance movement, Hamas, in Tehran Khaled al-Qudumi are among the participants in the conference.
The Zionist regime started a deadly offensive against innocent people in the Gaza Strip on July 8.
At least 2,016 Palestinians, including a large number of women and children, have lost their lives in the Israeli attacks so far and as many as 10,196 others have suffered injuries.
